MHW 612 "data-sheet" wanted
Hi,
I have constructed a VHF PA for 2m Band with MHW612, but the efficiency seems to be very low. Has anyone the "data sheet" of Motorola from that module? I was looking for around Internet without success. 73, Mak SV1BSX |

I was looking for around Internet without success. =============================== A few years ago I bought 3 pcs at a flea market (connection diagramme showing external components included) The diagramme shows . Supply voltage 12 -15 Input 200 mW @ 50 Ohms Output 20 W @ 50 Ohms. Would also be very interested in spec sheet. Question : Has this module linear characteristics ,hence can it be used for SSB or is it just for AM & FM ? Frank GM0CSZ / KN6WH |
